2008 NOV 17 - (VerticalNews.com) -- "[1] Regional air quality simulations are conducted at a horizontal grid resolution of 36 km for four summers (2001, 2002, 2051, and 2052) to examine the sensitivity of air quality to potential regional climate change in the United States. In response to the predicted warmer climate in 2051/2052, the emissions of isoprene and terpene increase by 20-92% and 20-56%, respectively, over most of the domain," investigators in the United States report ...read more

  2008 NOV 17 - (VerticalNews.com) -- "Greenhouse horticulture has experienced in recent decades a dramatic spatial expansion in the semiarid province of Almeria, in southeastern (SE) Spain, reaching a continuous area of 26,000 ha in 2007, the widest greenhouse area in the world. A significant surface air temperature trend of -0.3 degrees C decade(-1) in this area during the period 1983-2006 is first time reported here," scientists writing in the Journal of Geophysical Research - Atmospheres report ...read more

  2008 NOV 17 - (VerticalNews.com) -- According to a study from the United States, "We use a global chemical transport model (GEOS-Chem) driven by a general circulation model (NASA Goddard Institute for Space Studies GCM) to investigate the effects of 2000-2050 global change in climate and emissions (the Intergovernmental Panel on Climate Change A1B scenario) on the global tropospheric ozone budget and on the policy-relevant background (PRB) ozone in the United States. The PRB ozone, defined as the ozone that would be present in U. S. surface air in the absence of North American anthropogenic emissions, has important implications for setting national air quality standards. ...read more
